Symptom & Impact

System boots but graphical session never appears, leaving users blocked from desktop workflows.

Environment & Reproduction

Typically after kernel updates with incomplete NVIDIA DKMS rebuild.

Root Cause Analysis

Kernel and NVIDIA module versions diverge, so display manager cannot load required GPU drivers.

Quick Triage

Switch to TTY and verify NVIDIA module status and display-manager logs.

Step-by-Step Diagnosis

Check DKMS build records and Xorg or Wayland startup failures.

Solution – Primary Fix

Reinstall NVIDIA metapackage, regenerate initramfs, and reboot with matching kernel modules.

Solution – Alternative Approaches

Boot using previous kernel from GRUB advanced options or temporarily switch to nouveau for recovery.

Verification & Acceptance Criteria

Graphical login appears and nvidia-smi reports healthy driver/device state.

Rollback Plan

Purge NVIDIA drivers and return to open-source stack if proprietary modules remain unstable.

Prevention & Hardening

Stage GPU driver updates in canary hosts and ensure DKMS build checks before production reboot.

Related Errors & Cross-Refs

Related to Secure Boot module signing failures and mismatched linux-headers packages.
